I’m struggling to add a safe trade to the following strategy.

When I run the code, the safety trades are not put, even if the conditions are met.

In the example below, it should buy 2* the initial size if the price gets to -5%.

//@version=5
strategy("NEW", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=2)

// Input parameters
rsiLength = input.int(14, title="RSI Length")
rsiOversold = input.int(30, title="RSI Oversold Level", minval=1, maxval=50)
safetyTrade = input.float(5, title="Safety Trade Drop (%)", minval=0.1) / 100
takeProfit = input.float(5, title="Take Profit (%)", minval=0.1) / 100

// VARIABLES
var float avgBuyPrice = na
var float takeProfitPrice = na
var bool safetyTradeExecuted = false
var float safetyTradeSize = na
var float safetyTradePrice = na

// TA
rsi = ta.rsi(close, rsiLength)

// BASE ORDER
if (strategy.opentrades == 0 and rsi <= rsiOversold)
    strategy.entry("BUY", strategy.long)

// RECALCULATES
if (strategy.opentrades > 0 and not na(strategy.position_avg_price) and na(avgBuyPrice))
    avgBuyPrice := strategy.position_avg_price
    safetyTradeSize := strategy.position_size * 2
    safetyTradePrice := avgBuyPrice * (1 - safetyTrade)
    takeProfitPrice := avgBuyPrice * (1 + takeProfit)

// SAFETY TRADE 
if (strategy.opentrades > 0 and safetyTradeExecuted == false and close <= safetyTradePrice)
    strategy.entry("SFTY", strategy.long, qty=safetyTradeSize)
    safetyTradeExecuted := true
    // RECALCULATES
    avgBuyPrice := strategy.position_avg_price
    takeProfitPrice := avgBuyPrice * (1 + takeProfit)

// TAKE PROFIT
if (strategy.opentrades > 0 and close >= takeProfitPrice)
    strategy.close_all("TP")
    // RESETS
    avgBuyPrice := na
    takeProfitPrice := na
    safetyTradeExecuted := false
    safetyTradeSize := na
    safetyTradePrice := na
